Question

S is in between T and U. ST = x + 4 and SU = 2x. TU = 16. Find the value of x.

Answer 1

You know the total length ST and SU, so to find x you would write an equation. This would be: x+4+2x=16 Combine like terms: 3x+4=16 Subtract four from both sides: 3x=12 Divide both sides by three: x=4
